【摘要】：文章結(jié)合國(guó)內(nèi)外的研究,簡(jiǎn)要敘述了反芻動(dòng)物產(chǎn)生甲烷的機(jī)理、排放途徑,并著重綜述了國(guó)際上所使用的測(cè)定反芻動(dòng)物甲烷產(chǎn)生量的各種技術(shù),其中重點(diǎn)闡述了呼吸室技術(shù)、示蹤氣體技術(shù)、紅外光譜技術(shù)和微氣象學(xué)技術(shù)等。對(duì)于測(cè)定單個(gè)動(dòng)物釋放的甲烷來說,呼吸室技術(shù)所測(cè)得的結(jié)果是最為精確的,但由于造價(jià)相對(duì)較高,限制了其大規(guī)模的應(yīng)用;SF_6示蹤技術(shù)的應(yīng)用較為廣泛;微氣象學(xué)技術(shù)所測(cè)得的結(jié)果經(jīng)過校正后與呼吸室技術(shù)的測(cè)定結(jié)果接近;綜合考慮多種因素,紅外光譜技術(shù)因其檢測(cè)結(jié)果的精度較高且適用于多種條件,具有很大的發(fā)展?jié)摿��？傊?要根據(jù)測(cè)定的目的和實(shí)際條件等因素做出最合理的選擇。
[Abstract]:Based on the research at home and abroad, this paper briefly describes the mechanism and emission path of methane production in ruminants, and focuses on the various techniques used in the world to determine methane production in ruminants, with emphasis on respiratory chamber technology. Tracer gas technology, infrared spectroscopy and micrometeorology. For the determination of methane released by a single animal, the results measured by respiratory chamber technology are the most accurate, but because of the relatively high cost, its large-scale application is limited, and the application of SF_6 tracer technology is more extensive. The results measured by micrometeorology are close to those measured by respiratory chamber technique after correction. Considering many factors, infrared spectroscopy has great potential for development because of its high accuracy and applicability to various conditions. In a word, the most reasonable choice should be made according to the purpose and actual conditions of the determination.
